RECEIVING MECHANISM FOR TUBULAR TRANSIT SYSTEMS.

SPEGIFICATION formingpart of Letters Patent N 0. 669,888, dated March12, 1901.

Application filed July 10, 1900- To aIZZ whom it may concern:

Be it known that I, WASHINGTON A. H. Bo- GARDUS, a citizen of the UnitedStates, residing at The Montana, One Hundred and Twenty-fourth streetand Mount Morris avenue, in the city of New York, county of New York,and State of New York, have invented a new and useful Improvement inReceiving Mechanism for Tubular Transit Systems, of which the followingis a specification.

My invention relates to the general class of tubular transit systems,and more particularly to receiving mechanism therefor, consisting ofpneumatic means for checking the speed of and ejecting carriers from atransittube, and has for its object to provide a more simple, compact,and efficient operating mechanism therefor. This object I attain in themanner hereinafter set forth and particularly described, reference beinghad to the accompanying drawings, showing a vertical longitudinalsection of a receiving mechanism constructed in accordance with myinvention, as Figure I, and a detail of tripvalve, as Fig. 2.

Referring to the drawings, 1 is a section of incoming transit-pipe; 2,an enlarged portion thereof provided with ports 3, leading into anexhaust-pipe l. Areceiving-chamber5,forming a continuation oftransit-pipe 1, is normally closed at its outer end by a gate 6,operated by a piston 7 in cylinder 8. A receiving-table 9 is placed atthe exit of receivingchamber 5 to catch the carrier as it is ejectedtherefrom. A pistonvalve 10, controlling the movements of piston 7, isnormally held in its upper position (see Fig. l) by a spring 11,admitting air under pressure from enlarged portion 2 of the transit-pipe1 through pipe 14 to the top of piston 7 and reversed by the admissionof air under pressure to diaphragm 13, admitting pressure to the underside of piston 7 from the transmitter-pipe or an auxiliary supply.

The diaphragm 13 and valve are rigidly secured to a common valve-stem15. The

valve-stem 15 is extended without the casing of diaphragm 13 andprovided with a knob 16, forming a shoulder for engagement with alocking-pin 17 and also serving as a means of operating the valve 10 byhand.

The diaphragm 13 is connected by pipe 18 Serial No. 23,089. (No model.)

with a port 19, communicating with the outer vend of receiving-chamber5.

The locking-pin 17 serves as a valve-stem for a diaphragm 20 and isnormally held by spring 21 in a position to engage knob 16 of valve stem15 when said valve-stem 15 assumes its lower position. The outer end oflocking-pin 17 is extended through the easing of diaphragm 20 andprovided with a knob 22 for hand operation. The diaphragm 20 isconnected by pipe 23 with pipe 14: from transit-pipe 1.

A finger 24:, pivoted at 25 and provided with a projection 26 and aspring-pawl 27, normally seated on projection 26, is normally held inthe position shown in the drawings, projecting into the path of thecarrier at the outer side of the gate 6 by spring 28.

A valve 29, placed in the pipe 23 and having an annular recess 30, isnormally held in the position shown in the drawings by spring 31, itslower extremity extending a short distance below its casing.

The upper end of the stem of the valve 29 projects through the casingthereof and is provided with a knurled knob to allow of the operation ofsaid valve by hand.

As a carrier strikes finger 24; said finger is thrown up out of the pathof the carrier, the springpawl 27 riding under valve 29 and thenreturned by the actionof spring 28, the pawl 27 carrying the valve 29 toits upper position, allowing a momentary air-pressure to pass from pipe14 through recess 30 and pipe 23 to diaphragm 20 until the pawl passesfrom under the lower extremity of valve 29 and allows it to fall againunder the action of spring 31, cutting ofi the pressure from pipe 14 andexhausting pressure from diaphragm 20 through exhaust-ports 32.

Communication is always had between diaphragm 13 and port 19.

The operation is as follows: A carrier entering chamber 5 with speedfrom transitpipe 1 produces an excess pressure between its forward endand gate 6, which is communicated through port 19 to diaphragm 13,throwing it, with valve 10, down and opening gate 6. As the diaphragm 13is thrown down locking-pin 17 snaps under pressure of spring 21 behindknob 16 and holds the diaphragm 13 and valve 10 in this position untilthe carrier has passed the gate 6 and trip-finger 24, propelled bypressure from the line. The return of finger 24 by spring 28 causes thepawl 27 to raise Valve 29 momentarily, allowing a puff of air from pipe14: to pass to diaphragm 20, which acting against spring 21 Withdrawslocking-pin 1'7, allowing valve 10 to return to its normal position andclose gate 6. The return or fall of valve 29 exhausts diaphragm 20 andthe cycle of movement is complete, each moving part having assumed itsoriginal position ready for the reception 1 of another carrier.

It is obvious that various changes may be made in the construction anddetail of this device without departing from the spirit of my invention.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. In a receiving apparatus for transit-tube systems, the combinationwith a receivingchamber, a gate therefor and pneumatic operatingmechanism for said gate, a valve for controlling said pneumaticoperating mechanism, a spring normally holding said valve in oneposition, a diaphragm for throwing said valve to its other position,means of communication between said diaphragm and saidreceiving-chamber, and means for locking said valve in and releasing thesame from said latter position, substantially as described.
